Management Project of Environmental Protection. The Dayuandu Hub is a mluti-purpose project of the water resources. The retum water of the reservoir wili channel a 90-kin navigatabie course upper reaches and increase the navigable capacity of lower reaches so that to upgrade the course of Hengyang-Zhuz&ou from the present V navigable classification to 1!1 navigabie classification, and make the sail of 1000-tonage fleets available, the hydro-power station with 120 MW irstalling capacity wili generate about 53C million kwh annualty to relax thie tension of electricity supply, Vhe economic and ervironmental beneFits being obous. As for the bac Impacts of t7e prect on tne environment, we would try Our best to avoid and reduce them in the period of the constuction the project The construction engineeinng and its relevart environsm-Iental protect enginteeet oni tc  designed. constructed and operated at the same time phase by ohase and the Stres shatl be laid on both engineering supeNis;on and envirnmental supervo n both The report has put forward the strategies of preventon and treatment for the potertal imnpact on the ernronment by the en..ers in accrdance 'W"i t.e Evaluation Report of the Envirorimental Impacts on the Xiangping (hengyang-zhou) Novigational Corstuction Engineering. 3.1 The Engineering of Oayuandu Hub 3.1.1 Gonsideration on the flood conotr and the losses of submergence in the design phase: For reduceing submergence and bnnging no impacts on flood control of the -eservoir area, the selection of normal water stc:'age ieve and . . -.e . f the hub have been studied and demonstrated carefu[Nl The font of over,flwo, has been widened. he ! idh'. of .he 2i-Ottc sin.'s , overflow gate has been reduced as low as possible that almost be the same as the attitude of the origiral river bed so as to form a lower, opened gate dan- .when discharging the flood. to ensure the flood discharge in natural flow shape. To compare the water level of 20-year encounted flcod after the completion of the reservoir p..ject with the !evel of naturaf flood in same frequence. the dammini up just is 0.07-0-17mr The normal check level is decIded to be SOm (Huanghai Alitute). Tne water level of reservoir forrned by the upward reach of the dam fill be limited within the embankment that wouid just submerge 356 Chinese mu of farm larxdl of enjyoyng the repayment under the sts-e relevant stipulations. athouCh it .S a poor land for farm. 7  3.1.2 The impacts on the embankmnent of the reservoir by the rise of watr level The flood prevention dyke of Hengyg City ;n the .:ter danmed ama ws designed for 50-vear encounted flood and is in constructon. The enbankment of the resernoir area is designed for 20-year et-munted food. After te comnplon of te reservoir. the water level of the reach of Hengyang City wouid be rised 0.07rn and 0.17m at the front ofthe Dayuandu Dam by the 20-year encounted flood compared with that of the natural state. So, the impact of the water storage of the reservioir s very srnall on the flood control ability of the embankment of the tw banks of tme reach ard may be neglected if the thin dykes in a few sections have been reinforced and heightened property .Naw, the flood-control dykes in the area under the jurisdiction of Hengyung Municipal People's Govemrnment is being reinforced and the average 1 meter will be heightened . Ater the compeletion of the engireering, the flood preventon abi.lty of the dykes will be improved greatly. 3.1.3. Protection of the banks slopes Due to the rise of the water level wiening, the water surface after the. weater has been stored in the reservoir. the immersion time of th' bench terace of the reservoir banks would oe prolonged and the water erosion and water cut be more serious. So, it is necessary to adopt the stone masonry bank and the sloDed bank cavered by grass for the cuff bank and loose-soil bank to reinforce the dyke's safty. 3.1.4. Transform of drainage culverts and gates There are 66 drainage cu!verts and gates in the reseroir area. The present outlet base plates of them are lower so that they woul;J be submerged when the water level of the reservoir nsed tha will affect the their Cratnaae function of detained water and sewage- So, they shall be tronsformed and be equipped wzth needed facilities before the water s.orage of the reservoir. 8  3.1.5. The prevention of watertogging for land below tMe normal water level itn the e:mbankme.t There is 15,000-plus Chinese mu of !and below Me normal water level in the ernbanknent calcuLated according to the rneasurerental dwang, of which there is 600o-plus Chinese mu helong to Hengshan Cointy accountng for 2% of the total larmland of the county; 900 C,;inese mu to Hetngdong County, accounftrg for 1.3% of the total farm!aid of the county. These farm. land namnty scatter around Longying Port and .Huangni Pow of Hengshan County. After the Water leve of the reservior is ised, the level of underyround water of those areas would be atso nsed. Because the lands mentioned above are at ower place, the drainage of the watedioggi.g v. becone d1ifTicult so as to affact the outout of t1he crops. The different waterlogging shiall be treated by different way: Fcr the large area of f-c-g band, C.he snt practice of the area it shall adhere to the onncna!

The wate.r w,l be pumped into the reservoir from some cultivated land in loaver area which can't be discharged by itself and crops prograrm mTy tbe cbanged ad. sorne present cultivating lanc may be changed into fishery farm. About all, Measures mentioned above to be adopted ae foCr Keeping the local peopes iMng standard no lower than before 3.1.6 Protection of fishery resource After the hub has been co-npleted Ithe darn. vvuld be blocked t-e channel of fish m:igation so thsat the parent population can not rntcratea tC. trhe upard reaches for spawniltng that *R affect the rfztsheri resourccs.

Water pollution:The waste water of the engineering area mainly comes from the sands and stones proccessing system- It has been estimated the suspended solids density in the waste water, although diluted by the river water, wvill still surpass the standard. So. the waste water shall be settled in a settling tank before emission by the contractors. Noises Proveniffon: The noises in the engineering area are mainly caused by the ergineering machiriery and the proccessing of sands and stones. The noises happened irregularty, suddenly. u rsuccessively an-d very strongly. Because the engineering area is located at the open and wildness places more than 300 meters away from any villages, the impact wilU be very sm.all. But,for easing the trouble of noises on the staff members and worKers at the engineering ste, the contractors shall select the machinery with good performance, adjust the operation time property e.m. to arrange the wvrk with loud noises in the day time and make the noises source as far as away from the living quarters of the engineering area- The waste residue treatment: There will be waste earth and residue in large quatity at the engineering areas that shall be treated property and make the waste to be the useful. The contractors shall, in accordance with the require.ments of design of the engineenng, use the waste earth and waster residue to fill the low-lina lands close to the engineering areas or use that as the road meteriaL 't is est. atad that about 3-00- * Th.nese mu of lw-wying land will be transformed lito cultite frmland by the 10  returning the surface soil to farmlandc! measure (The earth throwng area refer to 4.1.4.c. the Summery Report) Air pollafion: the air pollution ove7 the engineering area is rnainiy caused by the tail gas discharge of the engineering machinery with the diese as their power and the dust of powder nratral of building, earthwork and tilling engineeing But the engineering sites are at o en places wth a dmtance to any w71ages and a natura damp condition. the air pollution will form no social effects. However because. the earthwork and stone mining should strip the surface of the soil and destroy the vegetative cover so as to cause the erosion of soil and fose of water and hurm the natural landscape. the contractor(s) shall plant trees and lay turf on the slopes after the engineeni.gs have been completed to prevent the loss of water and erosion of soil and to beatffy the envrronment. Tne pawder material shall not ?be pilled in the open air. 3.1
